Product details

128Kbit FRAM with 40 MHz SPI — why it was chosen for logging

The Ramtron FM25V01-G is a 128Kbit non-volatile ferroelectric RAM (FRAM) from the F-RAM series, organized as 16K × 8 bits and accessed through a 40 MHz SPI interface.

The FM25V01-G is listed as obsolete. For a BOM that already specifies this part, the only sourcing path is through independent distribution — stock is limited to existing inventory held by brokers and surplus houses. Any new design should move to a current-production FRAM or a pin-compatible serial SRAM/EEPROM alternative. There is no factory lead time to rely on, so a firm order commitment is the only way to secure units.

Sourcing the FM25V01-G through independent channels

For buyers who need to fill an existing BOM line, the FM25V01-G is sourced through our independent distribution network. Each unit is verified against the original manufacturer's markings and tested for basic functionality before shipment. We do not hold a standing inventory of this obsolete part; each request is handled as a spot-market procurement with a confirmed quote before any order is placed.

Frequently asked questions

What is the replacement for FM25V01-G?

The evidence does not list an official successor from Ramtron (now Cypress/Infineon). For a pin-compatible replacement, look at current-production FRAM parts in the same 8-SOIC footprint with 128Kbit density and SPI interface, such as the Cypress FM25V01A-G (if still active) or the Infineon EXCELON series. Verify the supply voltage range and operating temperature match your design before substituting.
